Oko Kukuthi Nento Ongayenza Nayo
Ukususela ekuqalisweni kweekhomputha zekhompyutha ekupheleni kwee-1970 kunye neyekuqala kwee-1980, kuye kwaba nzima kakhulu kumatshini womthunzi nomthi onamaqhinga ukuba asebenze kwizithuthi zawo, kodwa i-chip encane ebizwa ngokuba yi-ELM327 microcontroller inceda ukutshintsha loo nto.
Kuwo wonke ama-1980 ukuya phezulu kwaphakathi kwe-1990, bonke abenzi bemoto babe nemigangatho yabo kunye neeprotoksi, kwaye kwakuyintloko yamakhwenkwe kubachwephesha bezobugcisa ukugcina konke. Olu qalise ukutshintsha ngokusungulwa kwe- OBD-II , eyona mgangatho oye waqaliswa ngabazenzekelayo kwihlabathi lonke, kodwa izixhobo zokukhangela izakhono zisenokuhlawula amawaka eedola.
Kude kube yiminyaka embalwa edlulileyo, kunye neefayili ezisisiseko kunye nabafundi beenkcukacha zivame ukubiza ikhulu lamadola. Iifowuni ezilula zikwazi ukufunda nokucima ikhowudi, kodwa ngokungaqhelekanga zanikezela ukufikelela kwii-PID ezinokubaluleka ekuhloleni iingxaki zokuqhubela phambili kunye neminye imiba.
I-ELM327 yenkqubo encinci ye-microcontroller isisombululo esincinci esincinane esincinci esinceda i-bridge. Amadivaysi abasebenzisa lo mlawuli omncinci, njengeYongtek ELM327 i-Bluetooth scanner , abasayi kubamba ikhandlela kwizixhobo zokukhangela izakhono, kodwa bafaka ulwazi oluninzi ezandleni zaBeyers.
ELM327 Usebenza njani?
I-ELM327 i-microcontroller isebenza njengebhulorho phakathi kwekhompyutheni yangaphakathi kwimoto yakho kunye ne-PC yakho okanye ifowuni egcinwe ngesandla. U-ELM327 unako ukuthetha kunye ne-OBDII kwaye emva koko uthumela idatha nge-USB, WiFi, okanye i- Bluetooth , kuxhomekeke ekuphunyezweni okuthe ngqo.
I-ELM327 isekela inamba yee-SAE kunye ne-ISO protocol, kwaye iifayili ezivumelekileyo ze-ELM327 ziyakwazi ukunxibelelana nayiphi na imoto ye-OBDII. Umyalelo osetshenziswe ngu-ELM327 awufanelanga nomyalelo we-Hayes, kodwa zifana kakhulu.
Yintoni Ndingayenza Ngayo ELM327?
Ungasebenzisa i- ELM327 ifowuni ukukunceda ukuxilonga imoto yakho okanye iloli, kodwa ngokuqhelekileyo uza kufuneka enye i-hardware kunye nesofthiwe. Iifowuni ze-ELM327 zinokuxhumeka kwiikhompyutheni , ii-smartphones, iipilisi, kunye nezinye izixhobo ngeendlela ezininzi. Iinkqubo ezintathu eziphambili ziquka:
- Ukuxhumeka kwe-USB
- Uninzi olukhethileyo olukhethiweyo.
- Eyona nto ingabizi kakhulu ngenxa yokungabonakali kwerediyo.
- Akukho nethuba loxhumo oludibeneyo.
- Ikhebula linokungena endleleni.
- Ukunxibelelana kweWiF wireless
- Iyahambelana namadivayisi angaphezulu kuneBluetooth.
- Ixabiso.
- ibluetooth
- Ngokuthe tye.
- I-Bluetooth iyatholakala kwiinkcukacha ezininzi.
- Iyahambelani namanye amadivaysi, njengePhones.
Ukuba unayo i-PC okanye idivaysi ye-Android, nayiphi na ezo ziza kusebenza. Ukuba unayo i-iPhone okanye i-iPad, mhlawumbi ngeke ukwazi ukusebenzisa i-Bluetooth ELM327 idivaysi ngenxa yendlela indlela iOS ilawula ngayo i-Bluetooth stack. Izixhobo zeJailbroken zingasebenza, nangona oko kuthatha inqanaba lomngcipheko.
U-ELM327 unokukunika ukufikelela kwiinkcukacha ezinzima kwaye kukuvumela ukuba ukhangele i-PIDs. Ekubeni unxibelelwano luyi-bidirectional, i-ELM327 inokukuvumela ukuba ucime iikhowudi emva kokuba ugqibe ingxaki. Izenzo ezichanekileyo ozenzayo ziya kuxhomekeka kwisixhobo sakho esithile se-ELM327 kunye nesofthiwe oyisebenzisayo, kodwa unokukwazi ukujonga iindleko zokulinda kunye nolunye ulwazi.
Qaphela iiClones namaPirati
Kukho inani lama-clones kunye neengcambu kwiimarike, kwaye ezinye zisebenza kangcono kunabanye. I-v1.0 yasekuqaleni yekhowudi ye-microMroller ye-ELM327 yayingekho ikopi ekhuselwe ngu-Elm Electronics, eyabangela ukuba iphoswe. Ezinye iifowuni ezisetyenzisiweyo ikhowudi endala ziye zachitshilwa ukuba zisebenzise iinguqulelo zangoku, kwaye ezinye zize zitshintshe inguqulelo engatshatanga.
Amanye ama-clones angama-pirated azinzile, kwaye ezinye ziyi-buggy enkulu. Kwimeko nayiphi na, iifayile ezizinzile azikho ukusebenza okongeziweyo okufumaneka kwiinguqulelo ezintsha zekhowudi ELM327 esemthethweni.
Ukukhangela ezinye iindlela kwi-ELM 327
Ukuba ungathanda ukusebenzisa i-standalone ithuluzi lokuskena, kukho iindlela ezahlukeneyo eziwela kwiindidi ezahlukeneyo zamanani ahlukeneyo:
- Abafundi bekhowudi ezilula
- Ukwazi ukufunda nokukhupha iikhowudi kuphela.
- Izixhobo zokuskena ezinikezelweyo
- Iinqununu ezisisiseko zinika ukufikelela kwiikhowudi kunye nee-PID.
- Amanyathelo aphezulu aquka ulwazi lweengxaki.
- I-OBD-Ndiyisebenzisisa izixhobo
- Kubalulekile ukuba isithuthi sakho sakhiwa ngaphambi kowe-1996.
- Abanye basebenzisana neendlela ezodwa zokwenza imoto.
- Ezinye ziquka i-adapters zokusetyenziswa kunye neenqwelo ezininzi.
Ngelixa iifowuni ezisebenzisa i-ELM327 microcontroller zixhaphake kakhulu, indlela elula kakhulu yokutshintshela iikhowudi kunye nokujonga i-PID, kukho imeko apho enye yezi zinto zingentla ziza kusebenza kangcono. Ngokomzekelo, i-ELM327 isebenza kuphela ne-OBD-II, ngoko-ke i-ELM327 ithuluzi lokuhlola aliyi kukukwenza ukuba imoto yakho yakhiwe ngaphambi ko-1996. Ngaphandle kokuba ungumchwepheli ochwepheshayo, i-ELM327 ifowuni iya kusebenza kakuhle kakhulu kwezinye iimeko.
